Anyone know of a simple soft plastic lens cover?

I'm wishing someone made a simple soft plastic lens cover for my fz200. I'm thinking of something as simple as the cover to a cat food can... only it would be softer plastic and just push on to hold it in place.

I think the lens cap that came with the camera is difficult to use - and even worse it comes with the chance that it might scrape into the lens when trying to apply it to click into place.

The shallow sculpted handle is hard to grasp in the best of circumstances. I find it's almost impossible to grip if there's any moisture on my hand or with a glove.

I bought a protective filter so the lens won't get scraped - but it's a lot of trouble putting the lens cap on.

I searched online and couldn't find any totally simple push on lens caps.
